No. 11/833,817 filed on Aug. 3, 2007, which in turn is acontinuation of U.S. Provisional Patent Application No. 60/835,395,filed on Aug. 3, 2006, and U.S. Provisional Application No. 60/848,970,filed on Oct. 3, 2006, each of which is incorporated by reference hereinin their entirety.

FIELD OF THE INVENTION

The present invention relates to systems and methods for the placementand powering of video screens for the purpose of distributing real-timeinformation. Embodiments of the present invention relate to the relayingof advertisement information, operational information, and otherinformation by utilizing a satellite or other wireless communicationdevices and/or and local informational supplying devices.

BACKGROUND OF THE INVENTION

Companies rely on advertising to generate millions of dollars inbusiness from independent consumers each year. Companies often employ avariety of advertising techniques, such as electronic (television, radioand the internet) as well as still images (billboards or print media) todisseminate information about their products to potential consumers. Inorder to be successful, companies must place their information inlocations where it will be viewed by the largest number of potentialconsumers. In order to be successful in the advertising business,companies must develop strategies to reach the maximum number ofpotential customers with each type of advertisement.

Countless companies place their advertisements on electronic media to beviewed, perceived, or noticed by customers. An example is radioadvertisements that air throughout the day on commercial radio stations.This strategy may not be effective as many people switch to a differentradio station when commercials begin to air. In addition, as moreAmericans begin to utilize internet and satellite radio, the power ofradio advertisement will further decline.

Many companies also utilize television advertisements to increaseawareness about their products. This strategy, while effective, canpresent a cost prohibitive barrier to many smaller businesses. Companiesmust not only pay for the airtime on the network, but must also pay tocreate the commercial. The companies must also investigate the best timeto air their commercial so it will reach the maximum number of viewers.Network airtime during very popular shows can be very expensive for ashort time slot. In addition, with the advent of technologies such asTiVo® (TiVo, Alviso, Calif.) more people pre-record television shows andsubsequently skip the commercials.

Recently, companies have begun to advertise their products on the WorldWide Web. Advertisers can purchase space on popular websites to display“banner ads”. Consumers can click on the ad to be directed to thecompany's website or a retailer of the product. Many advertisers alsoemploy “pop-up” ads that open a new browser window when an individualvisits a particular website. Some consumers have found theseadvertisements to be annoying or intrusive and have employed pop-upblockers to block the advertisements or have switched to internetservice providers that do not use advertisements.

In addition to the various electronic advertising strategies, companiesalso employ still or print advertisements. Companies may employ avariety of media for placement of their advertisements. Companies willoften place their advertisements in newspapers or magazines. However,fewer consumers are obtaining their news from print sources as more andmore people turn to electronic news sources. Potential consumers may notsee the advertisements.

As individuals have become more mobile, companies have turned to the useof large print advertisements displayed in retail areas or along heavilytraveled highways. Retailers will often advertise their products withina shopping area, such as a mall, to attract customers to their stores.However, many businesses rely on advertising at locations remote fromtheir place of business. Often these retailers will place advertisementsalong major highways in an attempt to induce customers to visit theirlocation off of the highway. Technology has advanced within the lastdecade to allow for rotating billboards. These displays allow for morethan one company to place their advertisement on a single billboard, andthe image rotates at a pre-determined time interval. Some companies havealso begun to employ electronic billboards that display various ads onLED, LCD, or other types of display screens. Rotating and electronicbillboards, while more effective than single image billboards, cannot bechanged in real time with changes in the area.

In addition to billboards or other signage in retail areas, companiesmay also use their own delivery trucks to advertise their products whilethey are in transit. Still other retailers may place their informationon independently owned vehicles simply for advertising purposes.Customers can view the vehicles while traveling on the highway, and thisviewing can increase brand recognition. Currently, vehicles can bepainted with the advertisement or fitted with a billboard advertisementon the side of the vehicle. While many consumers may view the vehiclewhile traveling on the roadway, the signage is difficult to change if adifferent message is desired.

Thus a new way of delivering advertising content, as well as otherinformational content, to consumers and the general public is needed.

DETAILED DESCRIPTION

By way of example, in order to provide an understanding of theinvention, embodiments of the present invention are described withreference to a tractor trailer vehicle and a stationary billboard. Itshould be appreciated by the remainder of the disclosure herein, thatthe present invention is not limited to the embodiments described belowbut may comprise other embodiments for use with other vehicles,including, but not limited to, trucks, automobiles, motorcycles, boats,planes, barges, balloons, or similar vehicles designed for travel overland, air or water, as well as all-types of trailers in tow, or otherstationary screens.

Advertising is a dynamic business that must change in response tochanges in the social climate or pressures from the marketplace.Companies must continually update their advertisements to fit with thecurrent trends or desires of consumers. Current methods require asignificant time and monetary investment by the company to alter theiradvertisement. Thus, a faster, easier method to change advertisements isdesirable.

As society becomes more technologically advanced, consumers have come torely on real-time and current information. The use of cell phones andmobile devices capable of internet access has exploded in the pastdecade as Americans desire to be in touch at all times. A technologythat allows for real-time dissemination of information along highwayswould present an advance to consumers who wish to remain connected andto receive real-time information. Vehicles, screens, or billboardsequipped with a display according to embodiments of the presentinvention that display information in real-time could provide thedesired information to consumers.

Some advertising display systems may exist that provide for updateableinformation display. However, the conventional systems do not addressthe safety of individuals and drivers that view the display ofadvertisement. The conventional systems may create a moving safetyhazard because a fellow driver's attention may be distracted byreviewing the advertisement. It is desirable for a system of displayingadvertisements and other information in real-time while taking intoconsideration the safety concerns of fellow drivers. Embodiments of thepresent invention may provide greater safety protection for the driversand consumers. Embodiments of the present invention can enhance thesafety of consumers that are reviewing the advertisements or otherdisplayed information.

In one embodiment, the present invention provides a system comprising avehicle; a video display attached to the vehicle wherein the videodisplay can be positioned in a housing; a wireless data transfer devicewherein the wireless data transfer device comprises a wireless receiver,the wireless receiver being capable of receiving data transmissions; anoperational sensor device wherein the operational sensor device candetect changes in the operation of the vehicle; a controller wherein thecontroller receives signals from at least one source, the at least onesource comprising the wireless data transfer device or the operationalsensor device, and further wherein the controller can transmit signalsto the video display; and a plurality of power sources wherein at leastone of the power sources comprises a power source that is independent ofthe power supply of the vehicle. In some embodiments, the system maycomprise a video display that can be attached to a supporting frame. Thevideo display and supporting frame can be repositioned to provide anunobstructed entry and exit into the vehicle. In a further embodiment, avehicle may contain a retractable static advertisement. When the staticadvertisement is in the retracted position, at least one projector mayproject an image upon the blank screen. The retractor device and atleast one projector can have a sensor to trigger the operation of theretractor and projector.

In an embodiment of the present invention, a video display of varyingthickness may be affixed onto vehicles, such as tractor-trailer trucksas shown in FIGS. 1-13. As found in FIGS. 1-13, the video display can beattached by using different techniques and in different positions. Thedisplay may be of different sizes depending on the information to bedisplayed and the type and size of location of placement on a vehicle,screen, or billboard. The thickness of the video display may vary. In anembodiment where the video display is affixed to the vehicle, it ispreferable that the size and thickness of the display not impede safeoperation of the vehicle. A representative, but not to be consideredlimited, thickness of a video display for mounting on a vehicle is aboutthree inches. The possible types of video displays include, but are notlimited to, LCDs, LEDs, plasma screens, projection screens, CRT screens,optical fiber screens, and other display screens. The video display maybe powered by any number of different power sources, including, but notlimited to solar, wind, or a rechargeable power source.

In some embodiments, a system of the present invention comprises awireless data transfer device for receiving information transmitted byany of a plurality of transmitters, such as Bluetooth® technology(Bluetooth SIG, Inc., Bellevue, Wash.), satellites, cellular telephones,a wireless network, Wi-Fi, internet, or intranet. Information receivedby the wireless data transfer device may be communicated to the displaythrough the controller for displaying. The vehicle may also comprise aposition locating device, such as a GPS system, to determine thelocation of the vehicle. The information can be sent over air waves tothe wireless transfer device.

In another embodiment, information to be displayed is stored remotelyfrom the system, for example on a computer system and/or hard disk.Information from the computer system and/or hard disk may becommunicated to the system for displaying. In some embodiments, theinformation may be communicated over air waves. The hard disk/computersystem may be updated to provide new information for system and thevideo display. In a further embodiment, a wireless receiver can be usedto update the hard disk with new information.

In some embodiments, an operational sensor device can be used to detectchanges in the vehicle operation indicators and change the informationbeing displayed. An example, not to be considered limiting, of a vehicleoperation indicator is the application of the brakes of a vehicle. Inthis non-limiting example, when the brakes are applied, the operationalsensor device detects a stimulus (for example, the application of thebrakes), transmits a signal to the controller, the controller processesthe signal, and the controller transmits a signal to the video displayto display some defined message that indicates the brakes are beingapplied. Other examples of vehicle operation indicators can includeapplication of the accelerator, blinkers, direction indicator lamps,change of bearing, and other like indicators.

A video display of the present invention may vary in size depending onthe size of the vehicle. Video displays must be of minimal width to bemounted on the side or back of a vehicle. Due to their considerablethickness and weight, video display screens may need to be reduced inwidth. The width of the video display may not impair the vision of thedriver. In some embodiments, the width can be less than about threeinches. In other embodiments, the width of the video display can allowthe clearance of the roll-up back door. In some embodiments, videodisplays may be composed of a series of panels. In some embodiments thepanel construction can be utilized so as to not impair the functioningof the roll-up back door of the truck.

Typical LCD screens are eight inches in width, potentially too large andheavy to be mounted on the side of a vehicle. In order to accommodatemounting on a vehicle, an LCD screen may be broken down into itscomponent parts with only the screen being mounted on the side or backof the vehicle. It can be desirable to mount the other components of adisplay screen on other parts of the vehicle to prevent a weightimbalance created by mounting a heavy screen and component parts on theside or back of a vehicle.

In some embodiments, the video display may be attached to the rear ofthe truck and positioned on a supporting frame. In some embodiments, thesupporting frame can comprise horizontal members and vertical members.The supporting frame can provide a structure in which the video displaycan be mounted.

In some embodiments, the frame can be attached to the rear of thevehicle. The attachment device can comprise of a hinge or other likedevice. In one embodiment, at least one hinge can be attached to thevehicle and the supporting frame. The hinge can allow the supportingframe and the video display to be swung open around the central axis ofthe hinge to a position that does not interfere with the loading andunloading of a vehicle. In some embodiments, the hinge can be swung openaround the central axis of the hinge to about 90° from its closedposition. In some embodiments, the hinge can be swung open around thecentral axis of the hinge to about 110° from its closed position.

In some embodiments, the hinge may be oriented vertically so that thesupporting frame swings open to an orientation where the display screenof the video display remains substantially perpendicular to the ground.In other embodiments, the hinge may be oriented horizontally so that thesupporting frame swings open where the display screen of the videodisplay transitions to be substantially parallel to the ground. In someembodiments, the hinges oriented horizontally may be positioned on a tophorizontal member. In other embodiments, the hinges orientedhorizontally may be positioned on the top section of vertical members.

In some embodiments, when the hinge is oriented horizontally, it allowsthe video display to be substantially parallel to the ground's openposition, the video display may be repositioned on the top of thevehicle. In this embodiment, the hinge provides about a 90° angle ofrotation. When the supporting frame and video display are in the openposition, the supporting frame may be slid into a second framecomprising track bars.

In some embodiments, the video display can be displayed on the top ofthe vehicle. In some embodiments, the video display can be attached to arotating device. The rotating device is capable of rotating the videodisplay over a range of angles. In some embodiments, the range ofrotation can be 360°. In some embodiments, the range of rotation can beabout 180°. In other embodiments, the range of rotation can be about135°. In other embodiments, the range of rotation can be about 90°. Insome embodiments the video display can be rotated automatically oraccording to a pre-determined routine.

In other embodiments, the video display may be displayed on top of thevehicle in a stationary position. The video display may be flipped up sothat the display screen can be visible from ground level. In someembodiments, a hinge or like device can be used to reposition the videodisplay so that it may be viewed from ground level. In some embodiments,track bars into which a video display can be stored may be connected tothe top of a vehicle via a hinge or other like device. By reorientingthe track bars by using the hinge, the video display can be displayed toindividuals at the ground level. In yet other embodiment the track barsmay be positioned on a rotating device that rotates the entire track barstructure. By rotating the entire track bar structure, the video displaycan be visible from a plurality of positions on the ground level.

One exemplary embodiment of the present invention can be found inFIG. 1. FIG. 1 illustrates an embodiment of a system of the presentinvention. The vehicle 10 has the video display 12 attached to the side20 of the vehicle's trailer. The video display 12 can be connected to acontrol box 14. Within the control box 14, among other devices, acontroller, a wireless data transfer device, a power supply, and/or aposition locating device can be located. The connection between thevideo display 12 and the control box 14 can be provided by wires,cables, and other connectors known to one of ordinary skill in the art.In some embodiments, the connecting wires may be mounted along the sideof the vehicle, along the top of the vehicle, or along the back of thevehicle. In other embodiments, the connecting wires may be incorporatedinto the side 20. In some embodiments, wind turbines 18 and/or solarpanels 16 may be used as a mechanism to generate power for the system.Although, in the embodiment as shown, the control box is positioned onthe top 22 of the trailer, it should be understood that other placementconfigurations are possible including, but not limited to, positionssuch as behind the cab of a tractor trailer, inside a trailer, or anyother suitable locations.

FIG. 2 illustrates a top view of an embodiment of a vehicle with thevideo display 12 mounted to the side 20 of the trailer. In theembodiment illustrated in FIG. 2, the control box 14 is positioned ontop 22 of the trailer. The plurality of wind turbines 18 and the solarpanel 16 can be utilized to generate power for the controller and videodisplay to operate.

In one embodiment as seen in FIG. 3, a video display 28 can be attachedto roll-up door 26 positioned on the back 24 of the trailer. The videodisplay 28 can comprise of a plurality of panels. In FIG. 4, forillustrative purposes only and not to be considered limiting, the videodisplay 28 is comprised of four panels: 29, 30, 31, and 32. The videodisplay panels 29, 30, 31, and 32 correspond to the paneled constructionof the roll-up door 26. When the segmented, paneled roll-up door islifted into the open position, the paneled construction of the videodisplay 28 allows the display to mirror the operation of the roll-updoor, as illustrated in FIG. 5. FIG. 5 is a side view of a trailer asfound in FIG. 3 with a portion of the trailer cut away. The videodisplay panels 29, 30, 31, and 32 can roll-up in the same manner ofoperation as the roll-up door. The paneled, segmented construction ofboth the video display 28 and the rollup door 26 allow the transitionfrom a closed position (a substantially flat position) to a curvedposition (during the act of opening and closing as seen in FIG. 5) to anopen position (a substantially flat position).

Some video displays may be quite sensitive to jarring movements, such asthose experienced while driving. Without protection, some video displayscreens may quickly break due to the potential bumping and jarring as avehicle travels on a roadway. In some embodiments, in order to preventdamage to a video display, a screen may be positioned in a housingcomprising a protective case. The housing may reduce the level ofjarring or shocking by the vibrations of the vehicle traveling on aroadway. In some embodiments, the housing can comprise shock absorbentmaterial where the shock absorbent material decreases the forces actingupon the video display during the operation of the vehicle. In oneembodiment, a video display can be mounted such that it “floats” withina protective case and is not jarred by road movement. Enclosing a videodisplay in a protective case can also provide protection of the videodisplay from scratches, vandalism, or the weather. In some embodiments,the protective case can be made from a study plastic that istransparent, resistant to scratches, and can be easily cleaned.

Plastics that can be used include but are not limited to polymers suchas acrylics, various laminates, polypropylenes, polyethylenes,methacrylic polymers, polycarbonates, polystyrenes, cyclic olefinicpolymers, fluoropolymers, polyesters, polyarylates, polysulfides,polysulfones, other sulfur containing polymers, polymethylpentenepolymers, polyolefins polymerized with a metallocene catalyst,polyolefins, allylester polymers, polyamideimid polymers, fullerenepolymers, propylene-ethylene copolymers, other copolymers, and othertransparent polymers or combinations thereof.

The video display and other components can be powered by one or more ofseveral power sources, such as solar power, rechargeable batteries, orwind power. Where the video display is affixed to the vehicle, a videodisplay may be powered by rechargeable batteries that are recharged bythe engine of the vehicle, by solar power, or wind power. It isdesirable to provide an alternative power source for a video display sothat the screen does not diminish either the fuel or battery of thevehicle on which it is mounted. In an embodiment, the power can becollected by a power generating source, such as solar panels or windturbines and then stored in rechargeable batteries or a generator foruse by a video display, controller, and other devices. When affixed to avehicle, an alternate source power arrangement is also desirable so thatthe video display may continue to operate even when the vehicle isstopped or not turned on. In such embodiments, a video display maycontinue to display information even after the vehicle has stopped. Forexample, a video display may continue to display images or news afterthe vehicle has stopped to refuel or stopped for the driver to rest. Apower source for the system may be mounted on the top of a vehicle,along the front side of a trailer of a tractor-trailer truck, or othersuitable positions.

In order to display advertisements or information, a video display maybe connected to a wireless data transfer device via a controller toreceive data transmissions for display on the screen. Informationreceived by the controller may be relayed to the video display anddisplayed on the side or back of a vehicle. In a further embodiment, awireless receiver device may be positioned on the top of a vehicle toreceive transmissions from a plurality of transmission sources. Suchtransmission sources may include Bluetooth® technology, wirelesstransmitters, satellite transmitters, Wi-Fi, internet, or intranet. Datasignals may be transmitted from such devices to a transmitter located ona vehicle and further transmitted from a control box to a video displayscreen for display.

In some embodiments a vehicle may be equipped with a position locatordevice, such as a GPS device, to transmit the position or location of avehicle to a wireless or satellite receiving device. The positionalinformation of a vehicle can then be used to direct information that isspecific for, relevant to, and/or desired for the location of a vehicle.

In other embodiments, advertising information regarding specificproducts can be transmitted to a wireless receiver for display on avideo display screen. Such advertising information may be targeted orchanged depending on the location of the vehicle, screen, or billboard.Because the information is transmitted wirelessly, it can be updated inreal-time or changed at pre-determined intervals of time or distance.

In an embodiment, the information relayed to a wireless receiver mayinclude important news or traffic information that is relevant to theposition of a vehicle. Such information may include traffic reports,accident reports, or traffic delays. Other information may includebreaking news stories or public service announcements, such as AMBERalerts.

In a further embodiment, the information on the display screen affixedto a vehicle may change due to the transmission of a signal from anoperational sensor device connected to vehicle. The operational sensordevice can detect signals or information from a plurality of vehicleoperation indicators, such as, but not to be considered limiting,application of the brakes, the application of the accelerator, blinkers,direction-indicator lamps, change of bearing, and other like indicators.For example, but not to be considered limiting, when the vehicle isbraking, the operational sensor device would transmit a signal to thecontroller to interrupt the current video display information with asecond message. In one embodiment, upon the application of the brakes,an interrupting message notifies on-lookers or motorists that the brakesof the vehicle have been applied. The message may be a fixed or aflashing video display. The controller can receive the information orsignal and process the information or signal to determine theinformation or message to display on the video display. In someembodiments, when the vehicle is fully stopped, the controller can senda signal to the video display to display the product advertisementinstead of the interrupting message.

FIGS. 6a and 6b illustrate an exemplary embodiment where the videodisplay has changed as a result of the application of the brakes. FIG.6a depicts a vehicle that does not have the brakes applied. FIG. 6bdepicts a vehicle of FIG. 6a after the brakes have been applied as foundin video display 24. In some embodiments, the video display 12 may alsodisplay the interrupting message resulting from the operational sensordevice.

The operational sensor device can provide valuable information toenhance the safety of the onlookers. For example, the intermittent brakesignal notifies drivers of the slowing of a vehicle. In someembodiments, the time between the application of the brakes and thedisplaying of the message on the back of the vehicle is less than twomicroseconds. While an on-looker may be focused on the content beingdisplayed on the video display, the onlooker will not be able to dismissor ignore an interrupting message notifying him or her of an operationchange of the vehicle. For example, and not to be considered limiting,an onlooker would be unable to dismiss the message “BRAKING . . . Pleaseslow down” that appears in a large sized type and in some embodiments,flashing. The operational sensor device may transmit a signal via acircuit device used within the art.

In another embodiment, a display screen with a retractable staticadvertisement or informational display may be affixed to the vehicle.The display may be retracted upon the triggering of a sensor by aspecified stimulus. After detecting the specified stimulus, the sensortriggers a retractor device to retract the static advertisement. In oneembodiment, the sensor can be a light sensor. When the static displayimage is in the retracted position, a blank screen is present. The blankscreen may then be used as a surface to display a video image ofdifferent advertisements or information. The different advertisements orinformation may be displayed by at least one projector, LCD screen, orlike screen. The at least one projector, which may be positioned eitherat the side or rear, can be triggered by a sensor to project theadvertisement or information on the blank screen.

FIG. 7 illustrates one embodiment of the present invention. Therepresentative screen 36 is shown as a projector 38 and 40. Other typesof screens may also be utilized, including LED, LCD plasma, rearprojection, optical fibers, and the like. The screen may vary dependingon the size of the vehicle, and/or the screen may comprise individualpanels arranged to produce a large display. The display can be poweredby one or more of several power sources, such as solar power 16 or windpower 18. The lumination of the at least one projector may be from theside or rear of the screen. The screen is capable of displaying multiplemessages in multiple forms. The view indicates the presence of aretractable static advertisement 36. After the triggering of a lightsensor, a retractor device 34 retracts the static advertisement 36leaving a blank screen which is positioned behind a static advertisement36. When the static advertisement 36 is in the retracted position, asensor can trigger the at least one projector or LCD to display an imageonto the blank screen.
